is there a mode to split based on referencing to each other? eg: i declare a secret and mount it as volume in deployment => put them to a same file?

If you can code that into a Go template, then absolutely. It does seem however that this would require knowledge of the dependencies of resources.

For Kubernetes' own resources it might be easy to code. For CRDs, that's a whole other world.

One solution: annotate both the deployment and the secret, then use the name template to export them into the same file or, in other words, split based on annotations. Hope that helps!
